Customizable Size Marine Airbag 8 layer NBR Strong Load Capacity Anti Burst Easy Handling
Description
Our marine airbags for ship launching feature an advanced anti-burst design, using seamless rubber construction and reinforced ends for safety and longevity. The rubber is formulated for excellent resistance to saltwater, UV rays, and oil. Standard airbag sizes include 1.5×12m, 2.0×14m, and 2.5×16m, with custom builds on request. These airbags can bear heavy loads and are especially effective for launching vessels up to 10,000 DWT. Their flexible application across different terrains makes them highly popular in the shipbuilding industry.

FAQ
1. What is the recommended working pressure?
Typical working pressures range from 0.05 MPa to 0.25 MPa depending
on airbag size and layers.
2. How do I select the right airbag size and type?
Selection depends on ship weight, hull shape, and launching
environment. Our engineers can assist with calculations.
3. How many airbags are needed for one launch?
It depends on the vessel's length, weight, and the airbag’s load
capacity. Normally 6–12 units are used.
4. Do you provide custom-made airbags?
Yes, we offer fully customized airbags in terms of length,
diameter, pressure, and structure.
